Ciao bella gente, la situazione è questa:
Sede centrale più 11 sedi periferiche tutte in hdsl con una isdn di backup...
Per una di quelle il backup non vuole andare su...
Questa è la config del router periferico:

Sbaglio o manca il comando "backup" appunto, sotto la serial?!

E, comunque, messaggi più discorsivi aiutano a farci capire meglio.


Ciao.

Il comando backup...?!
Non basta la rotta staica?
Il problema è che se banalmente provo a pingare l' IP della punto-punto dell' altro router non va niente...

A me sembra che ci siano dei problemi sulla borchia nella sede remota...
Voi che dite?

prova a fare un test dalla sede remota, effettua un call:

isdn test call interface bri 0/1/1:1 32805.....

dove 32805..... è il numero del tuo cellulare. Vedi se partono le chiamate, cosi escludi il problema borchia.


Ciao

Era uno schifosissimo cavo il problema...
Grazie a tutti per l' aiuto!

Scusa Wizard
alcune considerazione un pò retrodatate
Perchè nel dialer di Verona vengono specificati 2 numeri da chiamare (dialer string)
e perchè nel router centrale ci sono 2 interfacce Bri ad accettare un eventuale connessione da Verona
Questo significa che lato centrale hai solo 2 borchie ISDN che vengono utilizzate all' occorrenza dalle 11 sedi periferiche ?

Grazie
